SPECIFICATION.

To all whom item1/concern.-

Be it known that I, ELLTOTT PENDLETON WEST, Of Jersey city, Hudson county, and State of N ew J ersey7 have invented a new and useful Improvement in Sewin g-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making a part of this specication and the letters of reference marked thereon, in which the sa me letter represents the same thing in each gure.

Figui-e l represents a side elevation of parts Of a sewing-machine with my improvements attached. Fig. 2 represents a front elevation Of the same. lFigs. 3 and lirepresent a section and side elevation of certain parts.

The object Of my invention is to enable the operator of a sewing-machine to speedily and handily lift the presser-foot thereof, and keep itlifted so long as convenience requires. This is effected by a lever, the-action of which is.

controlled by a plunger coming through the cloth or bed-plate of the machine near the hand of the operator. h

Ais the liiting-lever, pivoted on stud B to arm C, and connected at one end by slotted 'p tie-piece D to pin E in presser-foot bar F, and at the other by screw-pin G, connecting-piece H, pin I, and roclearm J tO shaft K, hung On The action is as follows: Pressing upon'the plunger N depresses lever M, turns shaft K, land arm J draws piece H and lever A, which lifts presser-foot P. A slight turn otplnnger N carries pin O beneath cloth-plate T and one side of slot S therein, and by preventing the plungers rise, holds presser-toot R up until the plunger is turned back and pressure taken therefrom, when spring It brings presser-foot P upon the material, land, by pin E and the connections before enumerated lifts plunger N. It is Obvious that the plunger may be placed elsewhere in the bed-plate, Or in the lower part of the arm Of the machine, whereever it can be most readily reached to actuate the lifting-lever.

That 1 claim and desire to secure by Letters Patent is The mechanism shown, consisting -Of lifting lever A, shaft K, and plunger N, connected and operated substantially as and for the purpose described.
